Chemistry Unit 2 – Finding Patterns-4 Abstract: This unit, Finding Patterns, takes an inquiry approach to understanding the patterns of properties that exist among the elements. These patterns in properties are then linked to the wave-mechanics concept of atomic structure and the quantum atom. Beginning with isotopes and average atomic mass, as a way of understanding the importance of the...

Document: Science Unit 3 (Revised)-3 Abstract: Unit three is Exploring Change, specifically bonds, energy, and reactions.  The change to be investigated will include indicators of chemical reactions as they relate to chemical bonding and energy changes. Chapters 7 and 8 cover ionic and covalent bonding respectively, while chapters 9 and 19 are the introduction to stoichiometry, chemical reactions. Again, a...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=304&id=304 Abstract: What is a googol?  Invented by Edward Kasner, an American mathematician who popularized the number in his 1940 book, Mathematics and the Imagination, it is a 1 followed by a hundred zeros. This directed case in estimation and very large numbers was written for a college-level introductory astronomy course, although it could also be used in a variety of...

Document: Human Fetal Growth Abstract:As an embryo grows into a fetus, size and mass are just two variables that will change over the 38 weeks.  Even though changes in size and mass do not occur at the same rate, an average mass and an average body length has been determined at various stages of development. From these two factors, an...
